i see what your saying but if a gen V is moving more air with the same amount of rotor rotation in the case...due to the design of the case itself wouldnt it therefore make more boost? i know you can port a gen III real good but only to a certain point correct? lemme know if im wrong thats just how i see it....
and i think you are correct about 20+ hp from this i dont think the new gtp's make 20 more horses off that blower its the blower plus a high compression motor....
